Naval Petroleum and Oil Shale Reserves. Annual report of operations, Fiscal year 1993

2008

During fiscal year 1993, the reserves generated $440 million in revenues, a $33 million decrease from the fiscal year 1992 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $207 million, resulting in net cash flow of $233 million, compared with $273...
